Abstract:
The present manuscript described the simple, rapid, accurate, sensitive, precise and economical Q- absorption ratio method for simultaneous determination of Cefixime and Moxifloxacin in combined tablet dosage form. Absorption ratio method uses the ratio of absorbances at selected wavelengths, one which is isoabsorptive point and other being the λmax of the one of the components. Cefixime and Moxifloxacin shows isoabsorptive point at 275nm in 0.1N HCl. The second wavelength used is 295nm, which is λmax of Moxifloxacin. The concentrations of the drugs were determined by using ratio of absorances at isoabsorptive point and at λmax of Moxifloxacin. The method successfully applied to the Pharmaceutical formulation because no interference from the tablet formulation excipients was found. The results of analysis have been validated statistically and by recovery studies.
